Computer-aided design of multi-purpose steel headframes for mines with a new technical level

Abstract

The existing steel structures of the sinking headgear and permanent headframe do not meet the requirements of resource saving (metal consumption and manpower input at installation), and the present methods of the headframe designing do not fully reflect recent possibilities of applying the advanced information technologies. The technical level of the modern software makes it possible for designers to set up multiple numerical experiments to create a computer simulation that allows solving the problem without field and laboratory experiments, and therefore without special costs. In this regard, a mathematical simulation and the software based on it have been developed. The software is designed to select cross-sections of multi-purpose steel headframe elements and to calculate proper weight of its metal structures depending on the characteristics and hoisting equipment. A headframe drawing is displayed as the result of the software work including list of elements and optimal hoisting equipment obtained in accordance with the initial data. The software allows speeding up graphic work and reducing manpower input in calculations and paper work. The software allows developing a three-dimensional image of the structure and its functional blocks, based on the obtained initial parameters, as well as developing control software for units with numerical control (NC) in order to manufacture multi-purpose headframes.
